To whom. it Quimera:

it known that l, Tnnononn .l. ENTE, oitren of the United States? andresident .W Yori; city, in the County oi New .State ot ll York, haveinvented fn naiv and useful improvements in Eat-tenes, of which thefollowing is Vation.

n' improvements in batteries and incre particularly to .d negativeplates and separators rihe main object et' the invention provide asimple and elicient arrange-l i' ".vhich positive and negative plates l.trom the oever of the storage bathave their free ends supportedterminal ends et plates et opposite v by means et insulating members ltop thereof, which insulating lso serve to support the separators pthereof.

and. advantages Will more clearly apfrom' the detail description givenbeletten in eonneetion with the aecomfing sheet. oit' drawings whichforms a r speoiiieation. ln the drawings, seetion through a storagebattery bedying niy improvements in a preterm thereof and Fig. 2 is asection sanietalren at right angles ot' Fig. 1. iz to the drawings, 3represents e. suitable glass container jar provided `with.

115 e cover 1ipregterably made ot an alloy et entnnony lead whereby itis seid-resisting. Cover Il is providedat its edges' `with a downwardlyextending ange 5 between which and the top oi" the jar 3 is arranged alayer of sealing compound; so that. the battery may be suitably sealed.6, 6 represent a plurality or set of negative plates and 7, 7 representaplurality or set of positive plates. The negative plates are prow videdwith upwardly extending members 8 at their terminal ends which connectwith a transverse bus bar 9 in turn integrally `vonneeted with aterminal lugl l() which passes through the cover 4. Where it passesthrough the cover e it is surrounded by a soft rubber bushing 11 on topof which is a hard rubber Washer l2 and e hard rubber 13 is screwed downon the termina-l ing order to hold the parts iirinly together.VSimilarlyy at terminal. ends'.

arrangement for supporting the posi-` neither and more specific objects,tea-- lvtheir upper the positive plates are provided with upwardlyextemlin'aq portions which are integ-rally connecte with a cross busmember which is connected to a terminal lult;r 15 passingup through thecover and where it passes through the cover, lit is surrounded by a softrubber bushing 16 on top of which is placed a. hard rubber Washer 17., Ahard rubber nut 18 is screwed down on the' out- Side end oit theterminal lug 15 in order te hold the part-s irinlytogether. In thecenter of the cover is arranged an opening for filling the battery whichopening is normally closed by a sott rubber'vent plug 19. At theirterminal ends the negative plates are provided with notches 2O intowhich extend the lower edge of a member of insulating material such asAhard rubber 21 which member extends transversely of the plates. y Thepositive plates at their free end are provided with hooked shaped arms22 extending upwardly from their upper edges and engaging over the upperedge of their insulating member 21. In this manner the insulatingmember. 21 is supported by the negative plates adjacent the upper edgethereof and in turn supports the free ends et the positive plates. Thepositive plates are provided With similar notches in their upper edgesat their terminal ends and extending into said notches and supported'thereby is a transverse rnen'iber of insulating material 23. Thenegative plates are provided at their free ends with hooked shaped arms2a extending upwardly from edges and engaging upwardly over their upperedge of said insulating member 23, so that the insulating member E23 issupported by the positive plates adjacent the upper edge thereof and inturn 9 supports the free end of the negative plates. 28, 28 representWood separators between adjacent positive and negative`plates, whichseparators are out away in their side edges adjacent the top thereof andthe insulating members 21, 23 pass through said cutaway portionsin theside edges ot the separatoriv whereby the separators are supported bythe plates through said insulating material members I The outsidenegative plates 6, 6 are provided with softrhbberiouttons 25 projeetinglaterally from the plates. These buttons 25 adapted to engage the sideet' the jar or container to prevent the body portions M0 .ico
